YARN-DYEING APPARATUS.

Specification of Letters Patent.

Patented Feb. 1, 1916.

Application led. June 4, 1915. Serial No. 32,058.

To all whom t may concern:

Be it known that l, JAMns J. FEARON, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Yarn-Dyeing Apparatus, of which the following is a specification.

My invention consists of certain improvements in the dyeing apparatus shown in my Letters `Patent No. 1,079,753, dated November 25, 1913, and No. 1,113,765, dated October 13, 1914, the objects of my present invention being to provide for a better circulation and distribution of the dye liquor during the dyeing operation and to facilitate the handling of the structure upon which the skeins or hanks of yarn are suspended, and the application of the yarn to and its removal from said structure.

These objects l attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which Figure 1 is a longitudinal section of dyeing apparatus constructed in accordance with my invention; Fig. 2 is a transverse section 01" the same; Fig. 3 is an enlarged view of the upper left hand corner of the dye tub and of the parts associated therewith; Fig. 4 is a like enlarged view of the lower left hand corner of the tub and of the parts associated therewith; Fig. 5 is a transverse section on the-line 5 5,Fig. 3; Fig. 6 is a transverse section on the line 6 6, Fig. 4, and Fig. 7 is a detached view'of part of the apparatus.

1 1 represent the sides, 2 2 the ends, and 3 the bottom of the dye tub, and 4 a transverse partition member within the tub which separates the dyeing chamber 5 of the same from the passage 6 containing the circulating device 7 whereby a flow of dye liquor, either in the direction of the arrows re or in the direction of the arrows y may be maintained. The dyeing chamber 5 contains the skeins or hanlrs of yarn which are to be dyed, the same being suspended from strips S at the top of the dyeing chamber.

Above the strips 8 is a screen 9 extending from end to end of the dyeing chamber and serving to distribute the flow of the dye liquor throughout the length of said chamber and above said screen is a passage 10 communicating at one end with the upper end of the passage 6 containing the circulating device, the lower end of said passage 6 communicating with the corresponding end ot a passage 11, which is separated from the dyeing chamber by means of a grid composed ct inclined transverse strips 12, alternately pitched toward the right and left, so as to form, between them, alternating spaces 13 and 13a, each open at top and bottom, the spaces 13 gradually widening from bottom to top and the spaces 13 gradually widening from top to bottom. Y

rlhe opposite ends ot' the yarn supporting strips 8 are seated in recesses in the top of opposite side bars 14 and the opposite ends of the screen forming slats 9, are adapted to openings in opposite bars 15, the bars 14 and 15 being connected by clips each composed, as shown in Fig. 5, of a lower member 14 and an upper member 15a, the lower member underlapping the corresponding bar 14 and the upper member overlapping the corresponding bar 15.

The bars 14 and 15 thus constitute a cage for the yarn supporting strips 8 and screen forming slats 9, and, by preference, the lower member 14101? each clip is secured to the lower bar 14 and is hinged as at 1G to the upper member of said clip whereby said upper member may be swung back free from engagement with the upper bar 15 when it is desired to separate the same and the slats from the lower bar 14 and the strips 8, in order to permit ready application or removal of the strips 8 with the hanks of yarn upon them.

When the upper member of the clip overlaps the upper bar 15 of the cage it may, il necessary, be retained in this position by means of one or more locking pins 25, as shown in Figs. 1, 3 and 5.

Mounted upon the top of the tub is a cover 17, having on the top, near each end, a transverse cross bar 18, which bars are connected by a longitudinal bar 19 provided with a hook or eye 20 (Fig. 7) 'for lifting purposes. On the under side of the cover 17, adjacent to each side of the tub, is a bar 21 which is secured to the corresponding top bar 15 of the cage, spacing blocks 22 being interposed between the bars 15 and 21 so as to maintain them in their proper relative positions.

By reason of the upwardly diverging spaces 13 in the grid at the bottom of the dyeing chamber the bottom portions of the hanks of yarn lying on top of the grid will not close said passages to the same extent that they do when the grid is composed of vertical strips disposed closely enough to provide proper support for the yarn, hence circulation oi' the dye liquor through the tub and either upwardly or downwardly through the dyeing chamber and the yarn therein is facilitated.

By making the cage which carries the yarn supporting strips S and the screen forming slats 9 in two parts temporarily retained in proper relation to one another, but readily separable, the cage with its load of yarn, may be supported upon suitable trestles outside of the tub, and the upper member of the cage, with the screen forming slats, can then be released from the lower member and applied to another lower member carrying a fresh load of yarn, the two members being then confined together and the fresh load oi yarn transportedto and lowered into the dye tub. When the members or' the cage are separated from one another the slats S, with the hanks of yarn thereupon, can be easily applied to or removed from the bars 14, and loading` and unloading of the tub is thus simplified and quiclrcned.

Mounted upon each side of the grid at the bottom of the dyeing chamber is a baiile plate 23 which extends some distance inwardly from each side of the tub and serves to direct the dyeing liquid to the center of the dyeing chamber and prevent it, either in its upward or downward course, from seeking the lines of least resistance at and near each side of the tub where there are no masses of yarn.

l. The combination of a dye tub having therein a dyeing chamber and a circulating passage below the same, with an interposed grid presenting passages whose sides alternately diverge from top to bottom and from bottom to top.

2. The combination of a dye tub having therein a dyeing chamberV and a circulating passage below the same, with an interposed grid composed of separated strips inclined alternately to right and left.

3. The combination of a dye tub having therein a dyeing chamber and a circulating passage below the same, with an interposed grid having balile plates at each side adjacent to the sides of the tub.

4. The combination of a dye tub having therein a dyeing chamber, yarn supporting strips, anda cage movable into and out of said dyeing chamber and comprising separable upper and lower members, the lower member having in its upper edges recesses for the reception of the ends of the yarn supporting strips and the upper member resting upon said lower member and serving to reta-in said strips in said recesses, and means for detachably connecting said upper and lower members of the cage.

5. The combination of a dye tub having a dyeing chamber therein, yarn supporting strips, a cage having separable members, the lower member carrying said yarn supporting strips, and clips for retaining said upper and lower members of the cage in proper relation to one another or releasing the upper member from the lower member.

6. rlhe combination of a dye tub having a dyeing chamber therein, yarn supporting strips, a cage having separable members, the lower member carrying said yarn supporting strips, and clips each composed of upper and lower members hinged together, one of said members being secured to its respective member of the cage and the other member being releasable from its member thereof.-

In testimony whereof I have signed my name to this specilication, in the presence of two subscribing witnesses.

JAS. J. FEARON.
